What is mChapters

mChapters is a simple and intuitive chapter marker editor for MP4, MOV, M4V, and M4A files. It allows you to easily insert, delete, and rename chapter markers—making it much easier to navigate long videos or audio files.

Chapter marker data—including times and titles—is saved as a text track in the file, following the QuickTime/MP4 specification. These markers can be recognized by compatible apps such as QuickTime Player, Music, TV, and other players on macOS.
They can also be used on iPhone, iPad, and Apple TV with apps that support the format. However, the Music app and the TV app (since iOS 12.3) do not appear to support this feature.
